AES Encrypt & Decrypt
AES-256-GCM with PBKDF2 key derivation — data never leaves your browser
Key is derived via PBKDF2 (200,000 iterations, SHA-256) — keep your passphrase safe.
Security details
- • Algorithm: AES-256-GCM (authenticated encryption)
- • Key derivation: PBKDF2 with 200,000 iterations, random 128-bit salt
- • IV: Random 96-bit nonce per encryption
- • The output includes the salt + IV — no separate key file needed
- • All processing happens in your browser via the Web Crypto API
